Say: 'I find nothing in what has been revealed to me that forbids any one to eat of any food except the dead, running blood, and the flesh of swine for these are unclean and that which has been hallowed in its slaughter to other than Allah. But whoever is constrained to eat of any of these, not intending to sin or transgress, then your Lord is Forgiving, the Most Merciful. 145 And to those who are Jews We prohibited every animal of uncloven hoof; and of the cattle and the sheep We prohibited to them their fat, except what adheres to their backs or the entrails or what is joined with bone. [By] that We repaid them for their injustice. And indeed, We are truthful. 146 So if they belie thee, say thou: Your Lord is Owner of extensive mercy, and His wrath shall not be turned aside from the guilty people, 147 Those who associate partners with God will surely say, "Had God pleased, neither we nor our fathers would have served other gods besides Him; nor would we have made anything unlawful." Likewise those who lived before them argued falsely until they came to taste Our punishment! Say, "Have you any knowledge? If so, produce it before us. You follow nothing but conjecture. You are merely guessing." 148 'Then say to them: '(As against your argument) Allah's is the conclusive argument. Surely, had He willed, He would have guided you all to the Truth. 149 Say, “Bring your witnesses who can testify that Allah has forbidden this”; then if they do testify, O listener (followers of this Prophet) do not bear witness along with them and do not follow the desires of those who deny Our signs, and of those who do not believe in the Hereafter and who ascribed equals to their Lord. 150
